Of all of the stories in Rob's book, Oprah says it was a passage about his wife, Sheryl, that moved her the most.

The passage reads: "And in the most surprising fact of my life, the one that at one point I thought I was incapable of feeling and unworthy of achieving, I am still in love with my wife. After almost 20 years of marriage, I look at her face and see her radiant light. I hold her and feel our hard-earned and sometimes difficult history passing between us, enveloping us in an aura of comfort, gratitude and profound attraction. If you'd asked me when I was a young punk what would have been the best thing that could have come my way, I would have said a movie with Martin Scorsese. But God had other plans. He gave me Sheryl."

"There's not a woman in America who wouldn't want her husband to say something like this about them," Oprah says.

What's it like being married to a sex symbol? "Even in our house, a sex symbol empties the trash," Sheryl jokes. "But truly, I don't see it like that. I see it as an amazing father, husband and partner. I mean, we've been best friends for 23 years."
